Dental, law, and CPA offices across your service area, inboxes verified before you send.
Search one vertical, like dentists or law firms, across the towns you serve. Each listing comes back with the owner's name where we can identify one, verified office inboxes where its website lists them, and phones checked for line type and carrier, ready to work in Close, Google Sheets, or Claude.

Why an IT pitch stalls before anyone hears it.
Bounces are a bad look for a security shop
When a bought list doesn't say which inboxes still exist, your first campaign finds the dead ones for you. Your sending domain takes the hit, which is an awkward look for a shop that sells email security.
The front desk screens for a living
Call a dental office, a law firm, or a dealership and you reach someone whose job includes keeping vendors out. "Is the owner available?" tells them you don't know who that is, and a phone tree or answering service puts you a step further away. Without a name and a sense of which line rings where, every dial starts cold.
One vertical, two dozen towns, all by hand
One vertical across the couple of dozen towns you'd send a tech to means a map search per town, a spreadsheet, and a contact-page hunt per office. By the time it's built the first towns are stale, and nobody wants to rebuild it next quarter.
From your service area to Monday's call list.
- 01
List the towns you'd send a tech to
Your service area is a drive time, and LeadMarina searches places like cities, not a radius. Write down the towns inside it: a north Dallas shop might list Plano, Frisco, McKinney, Allen, Richardson, and Garland.
- 02
Run one vertical across the list
Search "dentist" across the list in one bulk search: up to 250 cities, within your plan's daily city budget and as many as your lead balance can cover, with duplicates across towns removed. It runs in the background, and a full city typically takes minutes, longer under load. Then run "law firm," "CPA," and "insurance agency" the same way.
- 03
Split it into email and call lists
Save a view once and apply it to every vertical: principal-named offices with a safe inbox for the email sequence, established offices for your best caller, and mobile main numbers as a list of their own. On the established-offices view, change the review bar to suit each vertical. Phone 1 is each office's best confirmed number, so look in Phone 2 and Phone 3 for other mobiles.
- 04
Work it in Close, Sheets, or Claude
Export to Close, where each office becomes a Lead with a Contact carrying the owner name, Phone 1, and Email 1, or to a Google Sheet that leaves your own columns alone. Or connect Claude over MCP to query your All leads library for free and export from the chat.
- 05
Refresh the verticals you're working
Schedule a search to re-run monthly, up to 25 cities per automation (as many as your lead balance can cover on each run), and re-exports update Close and LeadMarina-created sheets in place instead of duplicating. Each run is a fresh search charged per lead delivered, including offices you already have, and it sends the whole result, not a saved view, so schedule only the verticals your team is working.
What the first call needs, in one row.
The principal's name, not "the owner"
We add the owner's name where we can identify one, usually because the business's own website names an owner, founder, or principal. It's a name only, with no title, personal email, or phone, and only a fraction of rows have one; listings with no website almost never do. Many practices and firms also carry the principal's name in the business name, and either one turns "Is the owner available?" into asking for Dr. Okafor by name.
Office inboxes, each one verified
Up to 3 emails per business come only from its own website, with no pattern guessing, and most are shared inboxes like info@, office@, and frontdesk@. Every email we find is verified and labeled safe, risky (a catch-all or disposable domain), invalid, or unknown, and invalid ones stay visible, marked red, so you can exclude them. Email 1 favors an address on the office's own domain, so a free webmail address there is worth a question about how the office runs email.
Line type hints at who picks up
Up to 3 phones per business, the Google listing's number plus any on the website, each checked for line type and carrier: a mobile most likely reaches the owner, a landline usually rings the front desk, and VoIP or toll-free is often a switchboard or call-tracking line. Line type describes the number, not the system behind it, so a Landline label doesn't mean an old phone system. Carrier is the carrier the number was originally issued to, since numbers get ported.
A second location or new associate, on their site
We crawl the homepage and a few inner pages, contact pages first and an about or team page when there is one, and an Excel download from the dashboard or a Google Sheets export carries the text of the first three (show the Page columns before a CSV; scheduled and API files leave the text out). Read them for something specific to say: a second location, a new associate, extended hours, or how they describe the practice. Page text can be read, sorted, and exported, but not filtered.
Reviews, standing in for a seat count
There's no seat count, device count, or employee count, so the Google review count is the proxy: a rough signal of how established and busy an office is. Review habits differ by vertical, so set your bar per vertical and confirm headcount on the first call.
Street addresses, for territory and site visits
Rows carry the address, city, and state from the Google listing. Sort by Address and listings in the same building land together, whether that's practitioners sharing one office or several practices you can visit in one trip; sort by Business and one name at several addresses points to a multi-site account. The default CSV leaves the street address out, so show the Address column or export to Excel.
Build the cut once, then set the review bar per vertical.
Filters you can build in a minute and save as a view, then apply to any search or to your whole lead library.
Principal named, inbox verified
- where Owner is not empty
- and Email 1 Status is Safe
Write to the owner or principal by name at an inbox that verified safe, then call and ask for them by name.
Established offices for your best caller
- where Reviews ≥ 100
- and Phone 1 Type is not Toll-free
- and Website is not empty
Review count isn't a seat count, but it's a rough proxy for an established, busy office; this view also skips toll-free main numbers, often a switchboard or call-tracking line, and keeps offices with a website to read first. Set the bar per vertical and confirm headcount on the first call.
Main number is a mobile
- where Phone 1 Type is Mobile
- and Website is not empty
When Phone 1 is a mobile, it most likely reaches the owner, which is worth a question about how the office handles its phones, and the website gives you something to read before you call. Mobile numbers carry stricter calling rules, so check what applies before one goes into a dialer.
Regulated offices, and the ones that run like them.
Dentists, clinics, and animal hospitals
Digital X-rays, practice-management software, and e-prescribing all depend on the network, and a practice that bills insurance electronically is a HIPAA covered entity; vets are outside HIPAA but run a similar setup. Individual dentists and doctors can have Google listings apart from their practice, so sort by Address to see which rows share an office. A practice affiliated with a DSO or a health system often has its IT handled centrally, so ask about ownership early.

Law firms, CPA firms, and tax preparers
Lawyers have a professional duty to protect client information, and tax preparers, including CPA firms that do returns, fall under the FTC Safeguards Rule, which requires a written information security program. Many firms carry their partners' names, which gives you a name to ask for. In a big metro, split law by practice area, since one search returns up to about 300 firms per city.

- Family law attorney
- Personal injury attorney
- Certified public accountant
- Accountant
- Tax preparation service
- Bookkeeping service
Insurance, title, and real estate offices
Many states' insurance data security laws require licensed agencies to keep a written security program, though the smallest are often exempt, and title and real estate offices sit in the path of wire-fraud attempts around closings. Individual agents can have Google listings of their own, so search "insurance agency" or "real estate agency" and sort by Address to find the office behind a cluster of agent listings.
- Insurance agency
- Insurance broker
- Title company
- Real estate agency
- Property management company
- Mortgage broker
Dealerships that finance or lease
Dealers that arrange financing or lease vehicles fall under the FTC Safeguards Rule, with its written security program, multi-factor authentication, and encryption requirements. Independent dealers usually decide locally, while a store in a dealer group often buys IT centrally, so ask about ownership on the first call. Lots and service drives also make them a fit for camera installers.

Most listings here have no website and an unclaimed profile, which can mean individual dentists listed apart from their practice, so sort by Address before you count accounts. With no site there are no crawled inboxes and almost never an owner name, and the phones are landlines, so work this market as a front-desk call list.

Nearly every clinic has a website, which is where inboxes, owner names, and page text come from. Most phones are landlines, likely a front desk, and the few mobiles are the rows most likely to reach an owner.

An opener written for a shared office inbox.
Hi {Owner},
I run [Your company], a managed IT provider in [Your town], a short drive from {City}. We look after offices like {Business}: the front-desk PCs and network, backups, email security, and the practice software everyone waits on when it's slow.
Plenty of offices already have someone, often a part-time contractor or a staff member fitting it in between other work. If that's working, good. If requests sit for days, nobody has tested a restore lately, or the last cyber-insurance renewal asked questions nobody could answer, that's the work we do.
Worth 15 minutes next week? I'll send a one-page list of what we'd check first, and it's yours either way.
If you'd rather not hear from me, reply "no" and I won't write again.
[Your name] [Your company] · [Your phone] [Your postal address]
Why it works
- Most inboxes we find are shared, like office@ or info@, so the office manager may read this first. It's written to be forwarded, with nothing that only makes sense to the owner.
- {Owner} is a full name with no title, and it's blank on many rows. Trim it to "Dr. Okafor" or a first name in your sheet, and open with "Hi all," when it's empty, since a shared inbox often has more than one reader.
- Swap "practice software" for the vertical: case management at a law firm, tax software at a CPA firm, the DMS at a dealership. Add one line from their crawled pages, like a second location or a new associate, before you send.
Before you send
CAN-SPAM covers commercial email to businesses, and calls and texts can fall under the TCPA and federal and state do-not-call rules, which are stricter for mobile numbers. If you also sell toner or ink by phone, the Telemarketing Sales Rule may apply, since its business-to-business exemption doesn't cover calls selling nondurable office supplies. LeadMarina doesn't scrub numbers against do-not-call lists or certify compliance, so check the rules that apply to you before you send.
Words in {braces} are columns in your export; words in [brackets] are yours to fill in.

Frequently asked questions
Can I filter by seat count, headcount, or revenue?
No. LeadMarina has no seat count, employee count, revenue, or tech-stack data. Review count is the closest proxy, a rough signal of how established and busy an office is, and category stands in for the kind of office, so treat both as proxies and confirm the seat count on the first call.
Can it tell me their current IT provider or phone system?
No. We don't identify an incumbent provider, a tech stack, or a phone system. Line type and carrier describe the number an office publishes, not what it rings on: a number labeled Landline may already have been ported to a hosted system, and carrier is the carrier the number was originally issued to. Ask on the first call.
Will I get the office manager's name?
No. LeadMarina finds businesses, not staff by role. The Owner column carries the owner, founder, or principal when we can identify one: a full name with no title, personal email, or phone, on a fraction of leads. In a small practice the office manager is often the one who deals with vendors, so ask the front desk for them by title.
Will I get every dental practice in my service area?
Not necessarily. Results come from Google business listings data, up to about 300 businesses per city per search, so an office without a listing won't appear and a dense category in a big metro can exceed the cap: split it into suburbs or narrower keywords like "pediatric dentist." One web-app search covers up to 250 cities, within your plan's daily city budget and as many as your lead balance can cover, while the REST API and the MCP server search one city per call.
If I schedule dentists monthly, do I pay again for offices already in Close?
Yes. Every scheduled run is a fresh search, charged per lead delivered, and it re-delivers offices you already have. In Close, GoHighLevel, or a LeadMarina-created Google Sheet those records update in place, matched on Google's business ID, instead of duplicating. Filtering and exporting leads you already have costs nothing.
Can it tell me which offices have had a breach or failed an audit?
No. No row carries breach history, audit results, compliance status, or cyber-insurance details, and we don't infer them. Category tells you which rules an office likely answers to, as the segments above describe; where it stands against them is a first-call question.
